Technical standards for power cords
The selection of the power cord is carried out according to some principles. Relevant requirements such as quality and appearance are also implemented in accordance with the power cord certification regulations. The principles for manufacturing power cords are as follows:
(1) According to the requirements for the selection of power transmission conductor cross-sections in the "Technical Regulations for Power System Design" SDJ161-85 issued by the Ministry, select the conductor cross-section of the DC transmission power line;
(2) "110~500kV Overhead Transmission Line Design Technical Regulations" DL/T5092-1999;
(3) "Technical Guidelines for High Voltage Direct Current Overhead Transmission Lines" DL436-2005.
